SLATE.

SPECIFICATION forming part of Letters Patent No. 33,725, dated August 5,1890. Application filed November 22, 1889. Serial No. 331,152. (ModeL)To all whom it may concern:

Be it known that I, THOMAS K. EWING, of Milwaukee, in the county ofMilwaukee and State of \Visconsin, have invented a new and useful Devicefor Teaching the Art of riting or Drawing; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,reference being had to the accompanying drawings, and to the letters ofreference markedthereon, which form a part of this specification.

In teaching very young children the art of writing or drawing it isfound to be necessary to educate the hand to make the required movementswith facility, correctness, and rapidity; and my invention relates to adevice especially adapted for use in kindergarten schools foreducating-the hand to construct the letters or designs that are exposedto view and which it is desired the child shall copy.

In the drawings, Figure 1 is aslate embodying one form of my improveddevice. Fig. 2 is a longitudinal section on line 2 2 of Fig. 1. Fig. 3is a book in which my device is embodied. Figs. 4 and 5 embody my devicein modified design.

My improved device consists of a plate or slate A constructed of stone,metal, silica, papierqnach, or some similar substance in the form of aslate, plate, or leaf, on which is printed or painted the letters,figures, characters, or designs which it is desired to have the childcopy. These letters, figures, designs, or characters are preferablyprintedorpainted on the surface of the plate or slate, as seen at B inFigs. 1, 3, and 4, and in connection therewith, and preferablyimmediately below the printed copy, is a duplicate thereof, as

seen at G in Figs. 1, 3, and 5, which duplicate is formed in the slateor plate by being cut or stamped into the slate or plate in intaglio.The printed characters seen at B are preferably of another color thanthe color of the slate or plate, being commonly in white when the slateis in a dark color or black, and the intaglio characters have the samecolor as the slate or plate, so that their lines and parts are notespecially, noticeable to the eye. It will be understood that by thisform of construccharacters by inserting the pen or pencil in theintaglio character and following its grooves or depressions in theproper direction, it being only necessary to instruct the childarbitrarily where to begin and in what direction to carry the pen orpencil to the completion of the character.

In the device shown in Fig. 1 the plate is inserted and secured in aframe D. In the device shown in Fig. 3 the plates A are bound in a book,with leaves E E inserted between them, the two plates A A beingpreferably located next to the cover F and being turned re'verselytoward each other, so that by swinging the book around and opening thebook to the plate and the intermediate leaves E E the plate will be atthe left hand and the leaves at the right hand, and in both instancesthe plate will be right side up. The leaves E E are perforated in a lineG near their inner edge, so as to be adapted to be torn from the bookafter being covered with characters. In the device shown in Figs. 4. and5the printed copy is on the independent plate A (shown in Fig. 4,) whilethe intaglio duplicate is on the independent plate A. (Shown in Fig. 5.)In each of these devices a portion H of the plate or slate is left blankfor the child to practice the making of the characters on a smoothsurface without the aid of the intaglio duplicates, and in the deviceshown in Fig. 3 the blank leaves E E are also intended and adapted forthe purpose of forming the characters thereon.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. As an article of manufacture, a slate havingletters, figures,characters, or other designs printed or painted thereon, and the samelotters, figures, characters, or designs in duplicate form in intagliotherein below the printed or painted letters, figures, characters, ordesigns, substantially as described.
